New Gaia Dynamic Routing features by release
- OSPFv3 AH authentication - support authentication for OSPFv3 protocol security
- IPv6 route aggregation - support aggregating routes in order to reduce the number of prefixes advertised to neighbor routers thus improving performance and scaling
- IPv4 NAT-pool routes - support NAT with routing by configuring and redistributing NAT-pool routes to routing protocols
- RIP route sync - re-implement RIP route sync in the standard way like the other routing protocols
- PIM restart - adds PIM to protocols which have user restarts
- BGP Support for VxLAN interfaces
- Dynamic Routing support for GRE interfaces
- Protocol Restart for BGP and OSPF
- Protocols can be restarted via WebUI or clish
- PBR in VSX
- Enables users to configure PBR rules and tables in a VS Context
- BGP Enhanced Route Refresh
- Enables support for Enhanced Route Refresh as per RFC 7313
- Gets enabled automatically when route-refresh is enabled
- IP Reachability MultiHop detection with ICMP and BFD:
- Multihop Ping and Multiple ISPs in Policy-Based Routing.
- Multihop Ping in Static Routes.
- BFD in Static Routes.
- VSX VSID in Netflow.
- OSPF v2/v3 Multiple Instances
- BGP IPv6 MD5
- OSPFv3 support in ClusterXL including Link-Local VIP
- BFD support for BGP and OSPF (IPv4 and IPv6)
R80.10 Advanced Routing and Clustering Enhancement Hotfix (which installs over R80.10) includes these same R80.20 Dynamic Routing features (along with R80.20 ClusterXL features). For more information about this hotfix, see sk122654.

General Limitations and Notes regarding Dynamic Routing and VRRP (for per-release limitations, see the release notes for your chosen release)
The two methods have different capabilities and different levels of integration with protocol-specific features. Routemaps are generally more capable but require all granularity to be configured within them. Also, if a Routemap is associated with a protocol (RIP/OSPF/BGP), it will take precedence over any Route Redistribution/Inbound Route Filters/protocol-specific features.
Route Redistribution can used to advertise certain routes with a specific MED to all BGP peers belonging to the same AS. Peer-specific configuration (med-out) can be used to advertise a different MED to one or more peers within the same AS. For those peers, med-out replaces the MED configured via Route Redistribution.
If a Routemap is also configured to advertise routes to BGP peers within the same AS, all Route Redistribution and peer-specific configuration is ignored.The Routemap must be configured completely to ensure that the required routes are advertised to all the peers with the MED desired.A peer-specific Routemap would need to be configured to advertise a different MED to a specific peer (see sk110477).
